We had another great experience working with EZ Test to buy our new hot tub. Trish and her team are very easy to work/deal with and she is very responsive. I highly recommend them. Thanks!

Carlos Maldonado

Met with Dave and Pat over 10 years ago to discuss buying a pool. We ended up buying and have been loyal customers since. I highly recommend the EZ Test for all your pool needs. We just bought a spa from EZ Test. Trish made the process easy. We could not be happier. We now trust EZ Test for our pool and spa needs!

I recently worked through EZ Test & D&P to install a fiberglass pool. Matt & team was extremely professional, had excellent communication through the entire process and delivered a fantastic product. Would definitely recommend it to my own family and friends.

A 5 Star Rating for E-Z Test Pool Supplies in Plaistow, NH. They are extremely knowledgeable and go out of their way to assist the customer. I call them “The Pool Guru” and would highly recommend them to anyone who needs help with their swimming pool, as I did. My problems are resolved now and my pool is crystal clear. Many Thanks!!!

Richard Morse

My husband and I walked into E-Z Test Pool, after being referred to by many people close to us, not knowing much about pools. We were greeted by Christina. She took her time to explain every pool to see which pool was best for us, how to maintain them, best products, and plenty of recommendations/how to’s. We successfully have an above ground pool (still filling up) and could not be happier! Highly recommend E-Z Test!
